Question:
Length of a side of an equilateral triangle and its perimeter vary inversely with each other.
Solution:
False
Length of a side of an equilateral triangle and its perimeter vary directly with each other, e.g. Let a be the side of an equilateral triangle. So,
perimeter = 3 x (Side) = 3 x a = 3a . So, if we increase the length of side of the equilateral triangle, then their perimeter will also increases.
